It can be recognized by its basal rosette of tessellated leaves with nar- row greenish white lines bordering the median vein. The most definitive, but not most convenient, character is the rostellar beak length, which lies between mm and 2 mm (Kallunki 1976). Description
. The Canadian field-naturalist. Natural history. 84 The Canadian Field-Naturalist Vol. 111 Goodyera tesselata Loddiges Tessellated Rattlesnake-plantain Goodyerie panachee Goodxera tesselata is a species of shaded forests and swamps, particularly on the Shield, that can form small, dense patches by vegetative reproduction. It can be recognized by its basal rosette of tessellated leaves with nar- row greenish white lines bordering the median vein. The most definitive, but not most convenient, character is the rostellar beak length, which lies between mm and 2 mm (Kallunki 1976). Description Height: 12(16-26)31 cm [114 plants]. Flowers: 8 (16 - 29) 35 [65 plants]; white, tending to face the brightest available light in a somewhat one-sided inflorescence; fragrance faintly spicy. Leaves: 2 - 5 on flowering and non-flowering plants, occasionally to 10 and rarely to 15 on non- flowering plants [48 plants]; - 4 cm long, - cm wide [18 leaves]; greyish green (not bluish green as is sometimes reported), with greenish white markings on upper surface only (see Figure), mark- ings occasionally broadened to cover most of leaf except directly over veins; occasionally 2 erect leaves at base of stem, occasionally lowest cauline bract expanded to form a small spatulate leaf. Overwintering State: as a rosette of leaves (see Vegetative Reproduction and Flowering Frequency below). Capsules: light brown, spheroid, typically x cm, ascending (see Figure la); yield highly variable but usually high, averaging 70% [14 plants]. Seeds: brownish orange, released in early September, a month earlier than our other Goodyeras. Blooming Period: 9 July (20 July - 15 August) 3 September [36 records]. Colony Sizes: 1 - 400, typically to 100, flowering and non-flowering rosettes [57 colonies], as scat- tered individuals, small clumps and patches of sever- al dozen rosettes. Distribution: The Ottawa District is well within. 76° 30' Goodyera tesselata: â = herbarium specimen,
